Important A unique case where uploading images do not work when using capital letters

I have found a difference when uploading images using upper and lower case (have not tried for other attachments).

Allowed image types set to the default (jpg, jpeg, gif, png) and upload myfilename.PNG, it appears to work but once saved and the screen refreshes the image does not display. Instead a missing image thumbnail is shown and no file was uploaded to the backend (I checked through cpanel) and no warning was provided saying that the file type was not accepted / uploaded.

If I rename the file to myfilename.png (lowercase png) all works as expected.

If I include PNG in the allowable image types ie (jpg, jpeg, gif, png, PNG) the response is the same as described above.

Thanks

Have you proven this by using the Playground category here?

Also, please read the important information at the top of this page. When reporting what you think is a defect, please include all relevant information, including your configuration report. The faster we obtain this information, the faster we can deal with the issue. If we have to remind people to read the important information that will help them , this only slows down the process.

In addition to the allowed MIME types in Kunena, there are also areas of your Joomla Global Configuration that you may need to examine, also.

Playground
- This will not help as I will have no way of knowing what the configuration of Kunena is nor will I be able to make changes to the configuration of Kunena nor the Global Configuration to validate any settings

MIME Types
- Have tried playing with this already. MIME Types on or off with PNG defined or not defined had no bearing

Global Configuration
- Never occurred to me that for a forum settings such as file extension, I would need to consider Global Configuration settings. If so, this should be referenced in the help text beside the image "Allow Image Type" field.
- Checked Global Configuration and cannot see anything in there that would or should affect the interpretation of upper vs lower vs proper case when uploading files.

As for reading the important information -- already done. That is the first thing I did and do each time in case anything changes in there .... That said, I have forgotten to include my configuration report.

My question to you is simple: can you create a message in the Playground category here and attach an image with the file type .PNG. This site uses a very standard configuration. If you can post your message with an attachment here, then we have a different issue compared with how your Joomla site is set up.

Of course it's possible that something may have worked before (in an older version of Kunena) and it doesn't work now. I would like to eliminate a functional defect before we go further with our diagnosis of your problem.

And, BTW, www.mydomain.com is not really your site, is it? :S If you edited your configuration report, that's your right to do so but it's also not very helpful to us trying to examine (or see problems as they occur in a "real" environment) if we aren't given information that assists us.

Yes it does work in playground.

Yes I did edit the domain name. This particular site is not open to the public.

The website here at www.kunena.org is built on a very standard J! 2.5 construction (obviously with one or two minor changes to ensure that certain things work as expected) but there have been no changes made to the Kunena configuration settings, PHP, Joomla that would impact on the inability to upload image with mixed-case filenames.

The point that I'm trying to make is that your website is as individual as any other website. We do not know, for instance, what version Apache software you are running. Your MySQL version is not one that I am familiar with, either.

Try using default Kunena configuration settings on your site. Try using the original Kunena menu that was setup for you. If these things do not work, try the When all else fails, try this approach. I think your case is an isolated case and, for this reason (because the symptoms are not able to be reproduced at this website) this is not, in the strictest sense of the word, anything to do with a defect of K 2.0.2. Perhaps there is a member of this community who may know more about what's happening at your website but, based on the information you have given us, I don't know more what to do.

I am moving this topic to a different category and I wish you good luck in finding help (even though no-one can access your website).
